My sister-in-law brought me the new Sartorial soap from London. I used it yesterday and it lathers beautifully, so I assume it is a new formulation, although I never used Pen's in the past and am going by the negative comments I read. My reference is my beloved D.R. Harris Arlington. This is comparable but I do not know if the price difference is justified. I will use it some more before drawing a conclusion. I really like the scent, but I can't describe it. It is beautifully packaged and they included a sample of Blenheim Bouquet EdT which I had to convince my wife was a men's cologne by explaining it was Churchill's favorite. I suppose I can justfy the cost by the amount of shaves one puck provides, but I will be surprised if I ultimately put it that far ahead of Harris, if at all.
